un-doing Sram power links

Ive got a Sram power link fitted to my Shimano chain.

My question... How do I undo it????

I've tried everything.

Obviously, because I fitted it I know how the power link works, and how it fits together.

It's just so tight. Tried fingers and thumbs. Won't budge. Tried some WD-40 on the link, but it's not having it lol

Have not got any tools small enough to get between the links, to add a bit of leverage.

Any suggestions?

    There's a neat trick in this month;s MBUK.
    What you do it get a piece of gear cable, and loop it round the two ends of the powerlink, then pull, and hey presto!

    Get a old cable and use that between the two pins.

    Once you get the nack of it you'll do it straight away every time.

    Just spay some wd40 on it first, then squeeze the connector while you push and it should pop straight out. Like i said theres a nack, but just remember to squeeze!

    Cool, even better! Will try that tomorrow :D

    I see what you mean about a 'Knack'. Guess I was squeezing in the wrong place :oops:

    loop string or cord through the ends then twist it to get tension, then press the sides of the powerlink? Or just grab hold of the chain either side of the powerlink push them together while pushing on th sides of powerlink with an index finger and thumb of both hands, works for me :wink:

    The SRAM power link, one of cyclings paradoxes if u ask me being both very simple and very difficult at the same time.

    It is a great idea none the less, why shimano dont use it or something similar is beyond me.

    Yeah, its a brilliant idea and they're a hell of a lot easier to undo than the KMC versions!

    Only once I've had a SRAM powerlink that I just couldn't get open. In the end I lost my rag, got the hacksaw out and cut through it. Took a while - hardened steel's pretty bloody hard surprise surprise!!! The chain was knackered and stretched and even when the powerlink was chopped in two I couldn't get it apart so it must of been seriously worn.

    Take care to keep them pretty clean - if grit gets behind the plates you can't easily push them together to take the powerlink apart.

    Also can someone explain the trick with the gear cable? I don't nor am I likely to have a copy of this months MBUK and its of interest!!

    You could always splash out and use one of these. Easily worth the money.

    I went back to using pins after having difficulty with sram links whilst out on a ride. I find it much easier to just use a chain tool to pop the bad link out and rejoin with a pin.

    Wahoo, more specialist tools, I like....much.
    It's easier to ask for forgiveness than for permission.

    I've bought a new bike....ouch - result
    Can I buy a new bike?...No - no result

    Yes it looks a worthwhile buy.

    I might just mutilate an old pair of needle nosed pliers with a grinder and rotary deburr, see if that works...

    ...and when it doesn't, I might buy one of those tools :lol:

    I've got a "special tool" for this, which is an old cheap pair of circlip pliars with the tips bent inwards, works a charm. Completely unneccesary of course but still, nice to have.
